Resizing System Volume Information (SVI) Windows only
Question: Sometimes your server might run out of space on because the SVI (System Volume Information) is eating up all memory. The system volume information is used in windows in order to save information related to system restore which is used when a restoration of the system is performed. The problem is that if there is no size limit to this feature, it might take a significant amount of the system memory, without ability to directly delete it. Answer: There are two ways to resize the SVI: Through the system properties - follow these instructions: http://www.pcadvisor.co.uk/how-to/windows/how-make-system-volume-information-folder-smaller-3613911/ Through the command line - if you don't see the system protection tab according to the above method, you can resize it through the command line: https://indrajitc.wordpress.com/2008/03/25/reclaiming-disk-space-from-system-volume-information/Connection Tool - Programmatically Remove Unused Datasource Connections, and List All Connections
Managing connections within your Sisense environment can become complex over time, if there are a large number of connections, and connections are often added, and replace earlier datasource connections. In some scenarios unused connections can accumulate, potentially cluttering the connection manager UI with no longer relevant connections. Although unused connections typically represent minimal direct security risk, it's considered best practice to maintain a clean, organized list of connections, and in some scenarios it can be desired to remove all unused connections. Sisense prevents the deletion of connections actively used in datasources, safeguarding your dashboards and datasources from disruptions. However, inactive or "orphaned" connections remain after datasources are deleted or a connection is replaced, potentially contributing to unnecessary UI complexity in the connection manager UI. Connections can be of any type Sisense supports, common types include various SQL connections, Excel files, and CSV files, as well as many data providers, such as Big Panda. This tool can also be used to list all connections, with no automatic deletion of unused connections.Update and add new Highcharts modules for use in Sisense plugins
Update and add new Highcharts modules for use in Sisense plugins The JavaScript library framework Highcharts is natively included in Sisense and is utilized in many native Sisense widgets as well as in numerous Sisense plugins. Although Sisense typically does not alter the Sisense Highcharts library version with every release, the versions of Highcharts included in Sisense may change when upgrading to a new major version release. Highcharts can load additional chart types and other types of functionality via JS module files that contain code-adding features such as additional chart types, which can be used within plugins along with additional code to create additional widget types. If a plugin utilizes a Highcharts module, you can source the module directly in the "plugin.json" file's source parameter, as shown in this example: "source": [ "HighchartModule.js", ], To determine the current Highcharts version being used in your Sisense version, you can use the "Highcharts" command in the web console while viewing any page on your Sisense server. After identifying the current Highcharts version, you can find the corresponding module hosted on the Highcharts code hosting website using the following URL format: https://code.highcharts.com/${Highcharts_Version}/modules/${module_name}.js For example: https://code.highcharts.com/6.0.4/modules/heatmap.js You can save this module and upload it to the plugin folder or replace the older module JS file simply by copying and pasting the code directly. Be sure to update the "plugin.json" file to point to the new module file if the file name has changed or if this is the first time the module is included. Simply sourcing the module file in the "plugin.json" file is sufficient to load the module into Highcharts; no further code is required to load the module.How to update style sheets in the branding folder for dashboards
In this article, we will address the issue of updates made to style sheets within a branding folder not reflecting on dashboards. Users often encounter this problem due to browser caching, which prevents the most updated CSS files from loading. This guide provides solutions to ensure your dashboard reflects the latest version of your style sheets.Error in ingress-nginx-controller pod after upgrading Sisense to L2024.1
Error in ingress-nginx-controller pod after upgrading Sisense to L2024.1: main.go:64] port 80 is already in use. Please check the flag --http-port !NOTE! - this guide is relevant for non-cloud managed Sisense deployments i.e. installed with Sisense Kubernetes (RKE). After upgrading Sisense to version L2024.1 you might face the following error in ingress-nginx-controller pod’s logs (the default namespace): main.go:64] port 80 is already in use. Please check the flag --http-port Such an issue might be the result of incompatibility between the ingress-Nginx release version that was updated in Sisense L2024.1 and the Kubernetes version in case it is lower than v1.26. In case Sisense L2024.1 was freshly installed on the non-cloud instance (i.e. with Sisense RKE) as a fresh deployment (and was not upgraded from the previous version) this issue should not reveal since L2024.1 package already comes with v1.26 Kubernetes by default. However, if Sisense was upgraded to L2024.1 or it was deployed/installed on Kubernetes lower than v1.26 there will be an incompatibility between the ingress-Nginx release implemented in L2024.1 (4.10.0). To resolve the issue it is necessary to re-run the Sisense upgrade with the following parameters in the configuration yaml file: update: true update_k8s_version: true In case you are still facing the same issue after that, please open a ticket for Sisense Support. This article provides a brief explanation regarding possible Nginx<->Kubernetes compatibility issues in Sisense L2024.1. The article also provides the steps to resolve the issue described.

Auto zoom Area Map widget to a specific country on load To test this solution, you must create a dashboard based on Sample ECommerce and an Area Map widget based on a Country column. Once it is done - please go to the widget editor, click three dots select Edit Script, then paste the following script there: As a result, we have our Area Map widget zoomed to Germany on the initial load: const countryName = 'Germany' widget.on('processresult', (scope, args)=>{ saveMapObj() }) widget.on('domready', (scope, args)=>{ zoomToCountry(L.geoJson(widget.queryResult.geoJson), window.currentMap, countryName); }) function zoomToCountry(geoData, map, countryName) { // Create a new empty GeoJSON object to store only the selected country's feature(s) geoData.eachLayer(function (layer) { if (layer.feature.properties.name === countryName) { map.fitBounds(layer.getBounds()); // Zoom to country bounds } }) } function saveMapObj() { let leafletHookStatus = $$get(prism, 'autoZoomAreaMap.leaflet.initHookAdded') if(!leafletHookStatus) { L.Map.addInitHook(function () { window.currentMap = this }) $$set(prism, 'autoZoomAreaMap.leaflet.initHookAdded', true); } } [ALT Text: A map of Europe with colored regions indicating specific areas.
